macOS is an advanced desktop operating system that fuels hundreds of millions of Mac devices on the market. macOS is Apple’s answer to Microsoft Windows and tends to get better and smarter every year. Apple’s macOS operating system has been through a number of major software updates since the launch day. Back in 2016, Apple unveiled macOS Sierra, the biggest macOS release that brought tons of changes to the operating system ranging from the ability to unlock your Mac from your Watch to Picture-in-picture mode in Safari.
Last year, macOS High Sierra spot the spotlight at Apple’s WWDC event. However, it came with small improvements as Apple put its focus on performance enhancements. At 2018 WWDC, macOS Mojave took center stage alongside iOS 12 and watchOS 5 following months of relentless rumors. Like its predecessor, macOS Mojave focuses on stability, but there are still a few surprises when it comes to Apple’s new version of macOS.
macOS Mojave has been around for three weeks only, but its problem reports have started to heat up. Indeed, a lot of macOS users are dealing with a number of macOS flaws ranging from issues with connectivity and app crashes to installation failed and unresponsive screen. Apple has acknowledged the issues and will address them in future updates. However, you can try re-installing macOS Mojave to see if the problem is fixed. Re-installing is a common practice when it comes to macOS as it helps fix some major issues. Doing so will reinstall your operating system only, meaning your user data or files remain the same. However, it’s a good idea to create a backup of your Mac in case something wrong comes up during the process.
You can back up your Mac using Time Machine. To do this, connect your hard drive to your Mac, then click on Apple logo at the top and select System Preferences from the drop-down menu. After that, select Time Machine, then click on Select Backup Disk and select your connected hard drive. Once you are done, click on Use Disk and turn on the switch.
